Microwave alkylation of lithium tetrazolate [PDF]

Monatshefte für Chemie - Chemical Monthly, 2016
N1-substituted tetrazoles are interesting ligands in transition metal coordination chemistry, especially in the field of spin crossover. Their synthesis is performed in most cases according to the Franke-synthesis, using a primary amine as reagent introducing the substitution pattern.

Photochemical Transformations of Tetrazole Derivatives: Applications in Organic Synthesis

Molecules, 2010
Tetrazoles remain a challenge to photochemists. Photolysis leads to cleavage of the tetrazolyl ring, may involve various photodegradation pathways and may produce a diversity of photoproducts, depending on the structure and conformational flexibility of ...

Hierarchically MOF‐Based Porous Monolith Composites for Atmospheric Water Harvesting

Advanced Materials, EarlyView.
This review explores the design of hierarchical porous materials for atmospheric water harvesting, focusing on metal‐organic frameworks (MOFs) and porous monoliths. Emphasis is placed on integrating MOF nanoscale porosity with the microscale channels of monolithic scaffolds to enhance sorption‐desorption performance.

Synthesis and Biological Evaluation of Bicyclic Pyrazolines with Promising Antimicrobial Activities. [PDF]

ChemMedChem
Continuous flow technology is exploited for the generation of bicyclic pyrazolines via photo‐click reactions. These heterocyclic species contain a valuable 3D scaffold along with a polar succinimide moiety. Subsequent antimicrobial testing reveals that halogenated moieties such as chlorine atoms and trifluoromethoxy groups enhance the potency of these ...
